How did Everything Become Neurodevelopmental?

Over the past two decades, an extraordinary shift has taken place in how we understand psychological distress, developmental difference, and everyday difficulty. Traits once described in the language of temperament, personality, coping style, anxiety, or adversity are now increasingly framed as manifestations of an underlying neurodevelopmental condition - most notably autism and ADHD.

This shift has occurred quietly, incrementally, and with good intentions. Yet its consequences are now visible everywhere: in schools, workplaces, clinics, families, funding systems, and in how people come to understand themselves and their children.

The question is no longer whether autism and ADHD are real conditions causing distress - they are - but how, and why, so much has come to be understood through this lens.

And this raises a further question, rarely asked directly:

What might be the unintended consequences of re-framing behavioural, psychological, or personality differences as neurodevelopmental, implicitly as immutable differences of the brain?

Historically, neurodevelopmental diagnoses were anchored to relatively clear developmental trajectories. Autism and ADHD were conceptualised as early-onset conditions - traditionally understood to emerge in early childhood - marked by differences in language, attention, social reciprocity, and self-regulation that were observable across settings and over time.

Over time, these categories expanded.

Diagnostic thresholds broadened. Developmental markers softened. Greater weight was placed on internal experience rather than observable behaviour. Subtler traits -sensory sensitivity, social fatigue, emotional overwhelm, difficulties with organisation - were increasingly interpreted as diagnostic evidence rather than as context-dependent or developmentally mediated phenomena.

Alongside this, a second shift occurred: diagnosis moved from being primarily a clinical conclusion to also becoming a meaning-making framework. Neurodevelopmental labels now frequently organise not only explanation, but identity, community, and moral understanding of the self.

This is not inherently problematic. People naturally seek narratives that make sense of their experience. But when diagnostic categories become the dominant explanatory lens, important distinctions begin to blur.

One of the most consequential changes in contemporary psychiatry has been the growing reliance on subjective report as diagnostic evidence.

This shift reflects genuine concerns: internal experience matters, and historically autism and ADHD, particularly in girls and women, were thought to be under-recognised within earlier diagnostic frameworks. However, there is a cost when assessment veers too far from observable developmental differences.

When retrospective self-reports of experiences that vary across contexts and are not specific to any single condition begin to qualify as diagnostic symptoms, we move into precarious territory - where it becomes increasingly difficult to distinguish between:

· neurodevelopmental difference

· anxiety and hypervigilance

· attachment adaptations

· trauma responses

· temperament and sensitivity

· regulatory capacity (e.g. emotion regulation, attention regulation, stress tolerance)

· personality traits (e.g. extraversion, conscientiousness)

· social learning in stressed or demanding environments

As diagnostic categories broaden, their discriminant validity weakens. That is, the diagnosis becomes less effective at distinguishing one kind of difficulty from another. The category absorbs more and more human variation, while becoming less precise about what it uniquely explains.

At this point, diagnosis does not simply identify difference- it begins to produce it.

To understand how this happened, it is necessary to zoom out.

Diagnoses do not operate in isolation. They exist within a diagnostic ecology: a system of interacting forces that includes clinical practice, research methods, educational policy, funding frameworks, advocacy movements, social media, and cultural narratives about suffering and responsibility.

Within this ecology:

· schools often require diagnoses to access support

· funding systems rely on a diagnosis and its “severity”

· parents face increasing pressure to advocate effectively

· clinicians are directed to “affirm” rather than question

· research increasingly relies on self-identified samples

· social media amplifies identity-based explanations over contextual ones

None of these forces are malicious. But together they exert directional pressure.

The system increasingly rewards diagnostic interpretation over developmental formulation, identity over context, and accommodation over growth.

Children at the Centre - and at Risk

Nowhere are the implications more significant than in childhood.

When a child struggles - emotionally, behaviourally, or socially - there is understandable urgency to help. Diagnosis can bring relief, validation, and access to resources. For many families, it offers coherence in the face of uncertainty.

But it also reshapes expectations.

A difficulty framed as neurodevelopmental is more likely to be understood as fixed, intrinsic, and enduring. The locus of adaptation shifts outward - from child to environment. The focus shifts away from supporting the child to develop emotional and regulatory capacity, and toward modifying the environment in order to minimise distress. Skill-building increasingly gives way to accommodation, and experiences that might once have been understood as developmentally expected challenges are more readily interpreted as harmful.

Over time, this can narrow a child’s developmental horizon.

This is not an argument against support. It is an argument for developmentally informed support - support that distinguishes between what is impaired, what is delayed, and what is still emerging.

When everything becomes neurodevelopmental, those distinctions are harder to sustain.

Academic research has not been immune to these dynamics.

As diagnostic categories broaden, research samples become increasingly mixed. Scientific concepts are often defined using self-report questionnaires that overlap substantially with anxiety, depression, and stress, raising questions about what these measures are actually capturing. When people are invited to endorse items that directly reflect the experiences they find most upsetting, higher scores are to be expected. Using such scores to justify claims about neurodevelopmental difference or environmental harm risks building the conclusion into the measurement itself.

Over time, a reinforcing loop can emerge. Broad diagnostic criteria group together individuals with very different experiences and difficulties. The resulting diversity of symptoms and presentations makes it harder to detect clear or distinctive patterns. When findings from such samples lack specificity, this is then taken as evidence that the expanded diagnostic category was warranted.

This is not a failure of individual researchers. It is a structural problem - one that calls for renewed attention to construct validity, methodological restraint, and developmental specificity.

These trends are further amplified by the attention economy.

On social media platforms, narratives that are emotionally resonant, identity-affirming, and morally unambiguous - offering clear reassurance about innocence and responsibility - spread far more readily than those that are cautious, conditional, or developmentally complex.

Neurodevelopmental explanations thrive in this environment. They offer certainty, community, and absolution. They transform struggle into belonging, reinforcing the idea that difference reflects a different kind of brain rather than a developmental challenge.

But ideas that travel fastest are not always the ones that support long-term wellbeing. When psychiatric concepts circulate widely, they tend to be shaped by what draws attention and reduces feelings of guilt or personal failure, rather than by what best reflects evidence or developmental understanding.

Increasingly, these concepts are circulated as a way to gain support, validation, and social visibility, as more people begin to recognise themselves in these descriptions

None of this is an argument for denying difference or minimising suffering. The expansion of recognition for genuine neurodevelopmental conditions has brought real benefits.

But recognition without discernment carries risks.

If every difficulty is framed as neurodevelopmental, we lose the capacity to ask essential questions:

· What is developmental, and what is the result of context?

· What requires accommodation, and what requires support to grow?

· What reflects enduring difference, and what reflects an adaptive response?

These distinctions matter - not only clinically, but ethically.

They shape how children are raised, how adults understand themselves, how resources are allocated, and how societies respond to vulnerability.

“How did everything become neurodevelopmental?” is not a rhetorical flourish. It is an invitation to examine the systems we have built - and the assumptions we no longer interrogate.

The task ahead is not to reject diagnosis, but to restore conceptual clarity in a landscape that has become crowded with meaning, identity, and urgency.

Development matters. Context matters. Methodology matters.

And if we are serious about wellbeing - individual and collective - we need frameworks that help people grow, not labels that help them belong.
